Development of Collaborative Engineering Environments for Spacecraft Design

摘要

The hazards of ionizing radiation in space continue to be a limiting factor in the design of missions,rnspacecraft, and habitats. Shielding against such hazards is an enabling technology in the human and robotic explorationrnand development of space. If the design of the radiation shielding is not optimal for the mission, then excess mass willrnbe launched, mission costs will be higher than necessary, and useful payload will be reduced. This reduced missionrncapability scenario can be repeated for other technical design disciplines. These other disciplines can also effect eachrnother's requirements. A collaborative engineering environment can optimize ALL design parameters for cost (or anotherrnparameter) producing a spacecraft that will meet all mission requirements at the minimum cost. This paper describes twornenvironments that include space radiation analyses and the inclusion within a larger optimization methodology.
